GDYJ-502
GOLD
Problem | How to solve GDYJ-502 |
|---|---|
The results of the insulation oil breakdown voltage test are inconsistent and have poor repeatability | Automatic mixing+waiting time+controllable pressure rise rate (multiple options), reducing human error |
Different standards (IEC, ASTM national standards) require different processes | Built in 8 standard testing modes, one click switch, no need to manually adjust parameters |
High safety risks for operators | High voltage chamber door safety switch+door opening power-off+reliable grounding design |
Test data cannot be traced or exported | Can store 100 sets of results+upload to PC via RS-232, export Word/print |
Details such as electrode gap and stirring are prone to errors | Supporting standard plug gauge (1/2/2.5/4mm)+magnetic stirrer+multiple electrode types |
Manufacturing enterprises of power transformers and circuit breakers: require batch testing of insulation oil quality
Substation and power plant operation and maintenance personnel: Regular on-site or laboratory oil testing
Third party testing agencies/oil laboratories: need to comply with multiple international standards (IEC/ASTM/BS)
Universities/research institutes: Research on material insulation performance requires programmable testing procedures
Counter Item | GDYJ-502 | Common Basic Voltage Resistance Meter |
maximum output voltage | 0-100kV | Usually 60kV or 80kV |
Built-in test standards | 8 types | None or 1-2 types |
Option for boost rate | 0.5 / 2 / 3 / 5 kV/s | Fixed rate |
Rest/Stir/Wait Time | 0-999s adjustable | No or fixed |
data storage | 100 sets | Usually absent or fewer than 10 groups |
PC communication | RS-232+dedicated software | No serial port printing |
safety protection | High-pressure door switch + Ground detection | Only grounding |
Note: The above is an objective summary based on the comparison of manual and common device functions, and is not specific to any particular brand
Multi standard integration
A device that meets 8 modes simultaneously, including IEC60156, ASTM D877/D1816, BS5874, and custom, is suitable for export or multivariate testing needs.
Clear operational safety
Automatic power-off when opening the high-voltage chamber door
Mandatory grounding reminder (must be grounded before starting up)
Oil free testing requires increasing electrode spacing to avoid damage
Data traceability
Automatically store 100 sets of test results
Support PC export and Word printing
Can record time, date, breakdown voltage, mean, and standard deviation
